Coarsening of facial features - Prognathism (jaw protrusion) and widened teeth gap (diastema) - Enlarged nose, lips, tongue (macroglossia) - Frontal bossing (enlarged brow) - Headache (tumor pressure) - Bitemporal hemianopia (optic chiasm compression by large adenoma) NECK/CHEST: - Deepened voice - Goitre (thyroid enlargement) - Cardiomegaly — biventricular hypertrophy - Hypertension HANDS/FEET (highlighted in red box — most classic): - Large spade-like hands — "ring no longer fits" - Large feet — "shoe size increasing" - Carpal tunnel syndrome (median nerve compression) SPINE/JOINTS: - Arthropathy, arthralgia — large joint pain - Kyphosis / vertebral fractures METABOLIC: - Diabetes mellitus / impaired glucose tolerance (40-50%) - Hyperhidrosis (excessive sweating — activity marker) - Sleep apnoea (soft tissue hypertrophy) - Skin tags (acrochordon) — associated with colonic polyps -

Macroadenoma (>10mm) in 75% - Assess: invasion, cavernous sinus, optic chiasm proximity ↓ STEP 5: Baseline hormone panel - Prolactin (co-secretion in 30%), LH/FSH, TSH, Cortisol, ACTH - Visual field testing (Humphrey perimetry) if macroadenoma Ectopic acromegaly workup box: "If no pituitary adenoma on MRI → measure GHRH → chest/abdomen CT for ectopic source" Lab pattern reference card (colored boxes): IGF-1: ↑↑ | GH on OGTT: fails to suppress | Glucose: may be raised | Prolactin: raised in 30% Cure criteria box (green border): "CURE = IGF-1 normal for age + GH < 1 ng/mL on OGTT + no tumor on MRI" --- ZONE 4 — BOTTOM LEFT (fresh green background) — STANDARD TREATMENT GUIDELINES Title: "Treatment Guidelines — Step-Up Approach" Treatment algorithm flowchart: CONFIRMED ACROMEGALY ↓ FIRST-LINE: SURGERY Trans-sphenoidal Surgery (TSS): - Cure rates: Microadenoma 80-90% | Macroadenoma 40-60% - Benefits: Rapid GH reduction, histology, decompresses optic chiasm - Best results: Small, enclosed tumors by experienced neurosurgeon ↓ POST-SURGICAL ASSESSMENT (at 12 weeks): Branch A (CURED): Monitor IGF-1 + GH annually Branch B (PERSISTENT/RECURRENT): Medical therapy MEDICAL THERAPY — 3 drug classes shown in side-by-side boxes: Box A — SOMATOSTATIN ANALOGUES (1st choice medical): Octreotide LAR: 20-30mg IM every 4 weeks Lanreotide Autogel: 60-120mg SC every 4 weeks MOA: Binds SST2/SST5 receptors → inhibits GH secretion Efficacy: GH control 55-65%, IGF-1 normalisation 45-55%, tumor shrinkage 20-30% Side effects: Gallstones (30%), GI symptoms (diarrhea, bloating), bradycardia, injection site reactions Monitoring: IGF-1 every 6 months, gallbladder USS annually Box B — GH RECEPTOR ANTAGONIST: Pegvisomant (Somavert): 10-30mg SC daily MOA: Blocks GH receptor → ↓IGF-1 production (does NOT lower GH) Efficacy: IGF-1 normalisation 90%+ Advantage: Works when somatostatin analogues fail; improves insulin sensitivity Side effects: Injection site reactions, liver enzyme elevation (monitor LFTs), may allow tumor growth (GH not directly blocked) Monitoring: IGF-1 (not GH!) monthly initially, LFTs monthly for 6 months Box C — DOPAMINE AGONISTS (adjunct): Cabergoline: 0.5-3.5mg weekly MOA: D2 agonist → modest GH suppression Efficacy: IGF-1 normalisation in ~35% (especially mixed GH/prolactin adenomas) Advantage: Oral, cheap, well tolerated Use: Mild residual disease, co-secreting prolactinoma, or combination with somatostatin analogues RADIOTHERAPY (last resort): Stereotactic radiosurgery (Gamma Knife/CyberKnife) Conventional fractionated radiotherapy Effect: Slow — GH normalisation takes 10-15 years Risk: Hypopituitarism (up to 50% at 10 years), secondary tumors rare Use: Surgery failed + medical therapy not tolerated/effective Treatment response monitoring visual timeline: Surgery → week 12 IGF-1 check → 6 monthly IGF-1/GH → annual MRI --- ZONE 5 — BOTTOM RIGHT (teal background) — SPECIAL POPULATIONS & COMORBID CONSIDERATIONS Title: "Special Populations & Comorbid Considerations" 6 colored sub-boxes: Box 1 — ACROMEGALY + DIABETES MELLITUS (orange border): - Prevalence: 40-50% of acromegaly patients - GH is insulin-antagonistic → insulin resistance → hyperglycaemia - Somatostatin analogues may worsen glucose (inhibit insulin secretion) - Pegvisomant: PREFERRED — improves insulin sensitivity, better glucose control - Avoid thiazolidinediones (fluid retention + cardiac risk) - Metformin and SGLT-2 inhibitors: safe and beneficial - Target HbA1c as per standard diabetes guidelines once GH controlled Box 2 — ACROMEGALY + HYPERTENSION & CARDIAC DISEASE (red border): - Cardiomegaly present in majority at diagnosis - Biventricular hypertrophy → diastolic dysfunction → HF risk - GH control reverses cardiac changes over time - Treat hypertension aggressively: ACE inhibitors / ARBs preferred - Screen with Echocardiogram at baseline and after treatment Box 3 — ACROMEGALY + SLEEP APNOEA (blue border): - Prevalence: 60-80% of acromegaly patients - Mechanism: Soft tissue hypertrophy of pharynx + tongue enlargement - Always screen with polysomnography - Treat with CPAP; acromegaly treatment reduces severity - Caution: Sedating pre-operative medications in untreated sleep apnoea Box 4 — ACROMEGALY + COLON CANCER RISK (purple border): - Skin tags = marker for colonic polyps - GH/IGF-1 excess → increased colonic polyp and cancer risk - Colonoscopy recommended at diagnosis and every 3-5 years - Normalize IGF-1 to reduce but not eliminate risk Box 5 — MEN1 ASSOCIATION (gold border): - ~3% of acromegaly is part of MEN1 syndrome - Screen for: Parathyroid adenoma (hypercalcaemia), Pancreatic tumours (Zollinger-Ellison) - Genetic testing: MENIN gene mutation - Family screening recommended Box 6 — PREGNANCY (pink border): - Rare; most patients have impaired fertility due to hypogonadism - Somatostatin analogues: Discontinue at conception (limited safety data) - Surgery before pregnancy preferred if possible - Monitor visual fields each trimester - Cabergoline: More data available; may be continued if benefits outweigh risks - IGF-1 physiologically elevated in pregnancy — unreliable monitoring marker; use GH instead BOTTOM FOOTER BAR (dark maroon, white text): 4 clinical pearls: "Surgery 1st line — cure depends on tumor size & surgeon experience" | "Pegvisomant: best for acromegaly + diabetes (improves insulin sensitivity)" | "Monitor IGF-1 not GH when on Pegvisomant" | "Colonoscopy at diagnosis — skin tags = colon polyp risk marker" Color scheme: Sky blue Zone 1, Amber Zone 2, Lavender Zone 3, Green Zone 4, Teal Zone 5.

Lanreotide Autogel 60-120mg SC every 4 weeks; MOA: SST2/SST5 receptor binding → inhibits GH; Efficacy: GH control 55-65%, IGF-1 normalisation 45-55%, tumor shrinkage 20-30%; Side effects: Gallstones, GI symptoms, bradycardia; Monitor: IGF-1 every 6 months, gallbladder USS annually Box B — GH RECEPTOR ANTAGONIST: Pegvisomant (Somavert) 10-30mg SC daily; MOA: Blocks GH receptor → reduces IGF-1 (does NOT lower GH level); Efficacy: IGF-1 normalisation >90%; Advantage: Works when somatostatin analogues fail, improves insulin sensitivity; Side effects: Liver enzyme elevation (monitor LFTs), injection site reactions; Monitor: IGF-1 (NOT GH) monthly initially, LFTs monthly for 6 months Box C — DOPAMINE AGONISTS (adjunct): Cabergoline 0.5-3.5mg weekly; MOA: D2 agonist → modest GH suppression; Efficacy: 35% IGF-1 normalisation (best for co-secreting GH/prolactin adenomas); Advantage: Oral, cheap, well tolerated RADIOTHERAPY (last resort): Gamma Knife/CyberKnife or conventional radiotherapy; Effect slow — normalisation takes 10-15 years; Risk: Hypopituitarism up to 50% at 10 years ZONE 5 — BOTTOM RIGHT (teal background) — SPECIAL POPULATIONS Title: "Special Populations & Comorbid Considerations" Box 1 ACROMEGALY + DIABETES (orange border): 40-50% of patients;

Landscape medical infographic for a visual clinical reference book. Topic: PROLACTINOMA. Professional, richly detailed, clean clinical design. White background. No chapter numbers. No zone labels. No layout annotations. Just pure clinical content organized beautifully. Header bar (deep indigo, white text): Large title "PROLACTINOMA" | Subtitle "Most common functioning pituitary adenoma | Benign lactotroph cell tumor" | Right side: "Prevalence: 100 per million" The infographic is divided into 5 clearly labeled content sections by their CLINICAL HEADINGS only: SECTION TITLED "ANATOMY & PATHOPHYSIOLOGY": Show the hypothalamus-pituitary-prolactin axis as a clean diagram. Dopamine from hypothalamus normally inhibits prolactin. TRH stimulates prolactin. Prolactinoma escapes dopamine control causing prolactin excess. Microprolactinoma <10mm vs Macroprolactinoma >10mm illustrated. Normal prolactin values shown. Prolactin level interpretation guide: 25-100 = drug/stress, 100-250 = micro likely, >250 = macro likely. SECTION TITLED "CLINICAL FEATURES": Female symptoms: galactorrhea (spontaneous milk), amenorrhea, oligomenorrhea, infertility, low libido, vaginal dryness, osteoporosis, headache, bitemporal hemianopia. Male symptoms: erectile dysfunction, infertility, reduced libido, gynecomastia, galactorrhea rare, headache, visual field defects (present late with larger tumors). Classic triad highlighted: GALACTORRHEA + AMENORRHEA + INFERTILITY. Note: Men present later because symptoms are subtler. SECTION TITLED "DIAGNOSIS": Step 1: Serum prolactin Step 2: Exclude secondary causes — pregnancy, hypothyroidism, drugs (antipsychotics, metoclopramide, SSRIs, opioids, verapamil, methyldopa), renal failure, PCOS, stress Step 3: MRI pituitary with gadolinium — gold standard Step 4: Visual fields if macroprolactinoma Step 5: Full hormone panel — LH, FSH, testosterone/estradiol, TSH, IGF-1, cortisol HOOK EFFECT warning box: Very high prolactin may give falsely LOW result — dilute sample 1:100 if suspected macro but prolactin appears normal. SECTION TITLED "TREATMENT": First line — Dopamine Agonists for both micro and macro: CABERGOLINE (preferred): 0.25mg twice weekly titrating to 0.5–1mg twice weekly, max 3mg/week. Efficacy: 80-90% normalize prolactin, 70% tumor shrinkage. Side effects: nausea, dizziness, cardiac valvulopathy at high dose. Monitor prolactin at 1 and 3 months. Echo if dose exceeds 3mg/week. BROMOCRIPTINE (alternative): 1.25mg nocte titrating to 2.5mg 2-3 times daily. More side effects, cheaper, more pregnancy data. Surgery (trans-sphenoidal): for drug resistance/intolerance, vision threatened, cystic tumors. Cure 70-90% micro, 30-40% macro. Radiotherapy (Gamma Knife): last resort only. Monitoring timeline: Month 1 prolactin, Month 3 review, Month 6 MRI if macro, Year 1 full panel + MRI, then annual. SECTION TITLED "SPECIAL POPULATIONS & COMORBIDITIES": PREGNANCY: Stop cabergoline at confirmed pregnancy. Microprolactinoma low growth risk — monitor symptoms. Macroprolactinoma 25% growth risk — visual fields every trimester, restart bromocriptine if growth occurs. Prolactin unreliable in pregnancy. DRUG-INDUCED HYPERPROLACTINEMIA: Antipsychotics (risperidone, haloperidol, amisulpride), metoclopramide, domperidone, SSRIs, opioids, verapamil. Switch to quetiapine/aripiprazole (prolactin-sparing) or add cabergoline cautiously. OSTEOPOROSIS: DEXA if amenorrhea >6 months. Dopamine agonist reverses bone loss. Add calcium + vitamin D. RENAL IMPAIRMENT: Prolactin elevated in CKD — interpret cautiously. Cabergoline: no dose adjustment needed. ELDERLY MEN: Start low dose cabergoline. Testosterone replacement may be needed adjunctively. Footer bar (navy, white text, gold accents): Key clinical pearls — "First line = Cabergoline, not surgery" | "Hook effect — dilute sample if macro" | "Stop cabergoline in pregnancy" | "Drug-induced: switch antipsychotic first" Rich clinical illustration style. Color coded by clinical section — blue for anatomy, orange for features, purple for diagnosis, green for treatment, teal for special populations. No zone names, no layout labels, no chapter numbers. Just clinical headings and medical content.

No layout annotations. Just pure clinical content organized beautifully. Header bar (deep burgundy, white text): Large title "ACROMEGALY" | Subtitle "GH excess after epiphyseal fusion | Pituitary somatotroph adenoma" | Right: "Incidence 3-4/million/year | Diagnosis age 40-45 years" The infographic is divided into 5 clearly labeled content sections by CLINICAL HEADINGS only: SECTION TITLED "ANATOMY & PATHOPHYSIOLOGY": Normal GH axis: Hypothalamus releases GHRH (stimulates) and somatostatin (inhibits) → anterior pituitary somatotroph → GH → liver → IGF-1 → peripheral tissues. Negative feedback: IGF-1 and GH feed back to hypothalamus and pituitary. Disease: Somatotroph adenoma (90%) causes unregulated GH secretion. Ectopic GHRH from pancreas or lung carcinoid (rare). Key distinction diagram: Before puberty (open growth plates) = GIGANTISM — proportional tall stature. After puberty (fused plates) = ACROMEGALY — acral and soft tissue enlargement, no height increase. Adenoma types: Microadenoma <10mm (minority), Macroadenoma >10mm (75% at diagnosis). IGF-1 = best screening test — reflects integrated 24-hour GH secretion. SECTION TITLED "CLINICAL FEATURES": Human figure with labeled acromegalic features: Face: coarsening, prognathism (jaw protrusion), diastema (teeth gap widening), macroglossia (large tongue), enlarged nose and lips, frontal bossing, headache, bitemporal hemianopia. Hands and feet (highlighted as MOST CLASSIC): large spade-like hands — ring no longer fits. Shoe size increasing. Carpal tunnel syndrome. Body: deepened voice, goitre, cardiomegaly (biventricular hypertrophy), hypertension, arthropathy, kyphosis. Metabolic: diabetes mellitus (40-50%), hyperhidrosis (excessive sweating — disease activity marker), sleep apnoea, skin tags (colon polyp risk marker), galactorrhoea if co-secreting prolactin. Red alert box: "THINK ACROMEGALY: increasing shoe/ring size + jaw enlargement + excessive sweating + new diabetes in middle-aged adult" SECTION TITLED "DIAGNOSIS": Step 1: Clinical suspicion from features above. Step 2: Serum IGF-1 — elevated = highly suggestive. Normal = effectively excludes acromegaly. Step 3: Oral Glucose Tolerance Test (OGTT) — GOLD STANDARD. 75g glucose load. Normal: GH suppresses to <1 ng/mL. Acromegaly: GH fails to suppress (paradoxical rise or no change). Step 4: MRI pituitary gadolinium-enhanced — assess size, cavernous sinus invasion, optic chiasm proximity. Step 5: Prolactin (co-secretion 30%), LH/FSH, TSH, cortisol, visual fields if macroadenoma. Ectopic source: If no pituitary adenoma — measure GHRH, CT chest/abdomen. Cure criteria: IGF-1 normal for age + GH <1 ng/mL on OGTT + no tumor on MRI. Lab summary: IGF-1 HIGH | GH fails suppression on OGTT | Prolactin raised in 30%. SECTION TITLED "TREATMENT": SURGERY — Trans-sphenoidal resection — FIRST LINE: Cure rates: Microadenoma 80-90%, Macroadenoma 40-60%. Benefits: Rapid GH reduction, histology, decompression of optic chiasm. POST-OP ASSESSMENT at 12 weeks: Cured → Annual IGF-1 and GH monitoring. Persistent/recurrent → Medical therapy: SOMATOSTATIN ANALOGUES (first choice medical therapy): Octreotide LAR 20-30mg IM every 4 weeks. Lanreotide Autogel 60-120mg SC every 4 weeks. MOA: Binds SST2/SST5 receptors — inhibits GH secretion directly. Efficacy: GH control 55-65%, IGF-1 normalisation 45-55%, tumor shrinkage 20-30%. Side effects: Gallstones (30%), GI symptoms, bradycardia. Monitor: IGF-1 every 6 months, annual gallbladder USS. GH RECEPTOR ANTAGONIST: Pegvisomant 10-30mg SC daily. MOA: Blocks GH receptor → reduces IGF-1 production. Does NOT lower GH itself. Efficacy: IGF-1 normalisation >90%. Advantage: Works when somatostatin analogues fail. Improves insulin sensitivity. Side effects: Liver enzyme elevation — monitor LFTs. Injection site reactions. Monitor: IGF-1 (not GH) monthly initially. LFTs monthly for 6 months. DOPAMINE AGONISTS (adjunct): Cabergoline 0.5-3.5mg weekly. Best for co-secreting GH/prolactin adenomas. IGF-1 normalisation ~35%. Oral and well tolerated. RADIOTHERAPY — last resort: Gamma Knife or fractionated radiotherapy. GH normalisation takes 10-15 years. Hypopituitarism risk up to 50% at 10 years. SECTION TITLED "SPECIAL POPULATIONS & COMORBIDITIES": ACROMEGALY + DIABETES (40-50%): GH is insulin-antagonistic. Somatostatin analogues worsen glucose. Pegvisomant preferred — improves insulin sensitivity. Metformin and SGLT-2 inhibitors are safe. Target HbA1c per standard guidelines. CARDIAC DISEASE: Cardiomegaly at diagnosis in majority. Biventricular hypertrophy — diastolic dysfunction. GH control reverses cardiac changes. ACE inhibitors/ARBs for hypertension. Echocardiogram at baseline. SLEEP APNOEA (60-80%): Polysomnography screening. CPAP treatment. Improves with GH control. Caution with pre-operative sedation. COLON CANCER RISK: Skin tags = colonic polyp marker. Colonoscopy at diagnosis and every 3-5 years. Normalising IGF-1 reduces but does not eliminate risk. MEN1 SYNDROME (3%): Screen for parathyroid adenoma and pancreatic tumours. MENIN gene mutation. Family screening. PREGNANCY: Discontinue somatostatin analogues at conception. Surgery preferred before pregnancy. Visual fields every trimester. IGF-1 unreliable in pregnancy — use GH monitoring. Footer bar (dark maroon, white text, gold accents): Key pearls — "Surgery first line — cure depends on tumor size" | "Pegvisomant preferred when acromegaly + diabetes" | "Monitor IGF-1 not GH on Pegvisomant" | "Skin tags = colon polyp risk — arrange colonoscopy" Rich clinical illustration style. Color coded sections — blue for anatomy/pathophysiology, orange for clinical features, purple for diagnosis, green for treatment, teal for special populations. No zone names. No layout labels. No chapter numbers. Clinical headings only.

Landscape medical infographic for a visual clinical reference book. Topic: CUSHING'S DISEASE. Professional, richly detailed, clean clinical design. White background. No chapter numbers. No zone labels. No layout annotations. Just pure clinical content organized beautifully under clinical headings. Header bar (deep purple/violet, white text): Large title "CUSHING'S DISEASE" | Subtitle "ACTH-secreting pituitary corticotroph adenoma → bilateral adrenal cortisol excess" | Right: "Most common cause of endogenous Cushing's Syndrome (70%)" SECTION TITLED "ANATOMY & PATHOPHYSIOLOGY": Normal HPA axis diagram: Hypothalamus → CRH → Anterior Pituitary Corticotroph → ACTH → Adrenal Cortex → Cortisol → negative feedback to hypothalamus and pituitary. Disease mechanism: Corticotroph adenoma produces ACTH autonomously — escapes negative feedback. ACTH stimulates bilateral adrenal hyperplasia → chronic cortisol excess. Important distinction box: CUSHING'S DISEASE = Pituitary ACTH excess (70% of Cushing's syndrome) CUSHING'S SYNDROME = Umbrella term for all causes of cortisol excess: - Pituitary (Cushing's disease) 70% - Adrenal adenoma/carcinoma 15% - Ectopic ACTH (lung, carcinoid) 10% - Iatrogenic (exogenous steroids) — most common overall Adenoma: Usually microadenoma (<10mm) in 90% of Cushing's disease SECTION TITLED "CLINICAL FEATURES": Central obesity body map with classic labeled features: FACE: Moon face (rounded), Plethora (facial redness), Acne, Hirsutism NECK/UPPER BODY: Buffalo hump (dorsocervical fat pad), Supraclavicular fat pads, Thin skin with easy bruising ABDOMEN: Central/truncal obesity, Wide purple striae (>1cm) — most specific sign LIMBS: Proximal muscle weakness (myopathy) — cannot rise from chair, Thin limbs, Peripheral edema METABOLIC: Hypertension (80%), Hyperglycemia/Diabetes (40-50%), Dyslipidemia, Hypokalemia (especially ectopic ACTH) BONE: Osteoporosis, Vertebral fractures, Avascular necrosis of femoral head PSYCHOLOGICAL: Depression, Cognitive impairment, Psychosis, Insomnia REPRODUCTIVE: Oligomenorrhea/amenorrhea, Reduced libido, Infertility IMMUNE: Increased infections (immunosuppression), Poor wound healing Classic clue box (red border): "PURPLE striae + PROXIMAL MYOPATHY + HYPERTENSION in a young person = investigate for Cushing's" SECTION TITLED "DIAGNOSIS": Two-phase approach clearly shown: PHASE 1 — CONFIRM CORTISOL EXCESS (any one of three): Test 1: 24-hour urinary free cortisol (UFC) — elevated on 2 separate collections Test 2: Late-night salivary cortisol (11pm) — elevated on 2 collections (cortisol should be lowest at midnight) Test 3: 1mg overnight dexamethasone suppression test (DST) — give 1mg dex at 11pm, measure cortisol at 8am. NORMAL: cortisol suppresses to <50 nmol/L. ABNORMAL: fails to suppress. PHASE 2 — DETERMINE CAUSE: Plasma ACTH: ACTH LOW (<10 pg/mL) = ACTH-independent → Adrenal cause → CT adrenals ACTH NORMAL/HIGH (>20 pg/mL) = ACTH-dependent → proceed: CRH stimulation test: Cushing's disease shows exaggerated ACTH and cortisol response. Ectopic ACTH shows no response. High-dose DST (8mg overnight): Cushing's disease SUPPRESSES (>50% cortisol fall). Ectopic ACTH does NOT suppress. MRI pituitary: Microadenoma in 60% (may be too small to see — normal MRI does not exclude) Inferior Petrosal Sinus Sampling (IPSS): Gold standard for confirming pituitary source when MRI negative — central to peripheral ACTH gradient >2 basal, >3 after CRH confirms Cushing's disease SECTION TITLED "TREATMENT": FIRST-LINE: Trans-sphenoidal surgery (TSS): Cure rates: 70-90% for microadenoma, 50-60% for macroadenoma Post-op: Transient adrenal insufficiency expected — cortisol replacement needed until HPA axis recovers (months to years) Remission criteria: Morning cortisol <50 nmol/L in first post-op week PERSISTENT/RECURRENT DISEASE — Medical therapy (4 drug classes): STEROIDOGENESIS INHIBITORS (most used): Metyrapone: 500mg-6g/day in divided doses. Blocks 11-beta-hydroxylase → reduces cortisol. Fastest onset. Side effects: hirsutism, hypertension, hypokalemia, nausea. Ketoconazole: 200-1200mg/day. Blocks multiple adrenal enzymes. Side effects: hepatotoxicity (monitor LFTs), drug interactions, teratogenic — AVOID IN PREGNANCY. Osilodrostat (Isturisa): 2-30mg twice daily. New potent 11-beta-hydroxylase inhibitor. More effective than metyrapone. Side effects: hirsutism, adrenal insufficiency, QTc prolongation. Etomidate: IV only — used in acute severe Cushing's crisis in ICU. PITUITARY-DIRECTED THERAPY: Pasireotide (Signifor): SST5 agonist — reduces ACTH from corticotroph. 0.6-0.9mg SC twice daily. Side effects: Hyperglycemia (very common — 70%), GI symptoms, gallstones. GLUCOCORTICOID RECEPTOR BLOCKER: Mifepristone (Korlym): 300-1200mg/day. Blocks glucocorticoid receptor — reverses cortisol effects without lowering cortisol. Cannot monitor cortisol for dose adjustment. Side effects: adrenal insufficiency symptoms, hypokalemia, hypertension, anti-progestogenic effects (endometrial thickening). BILATERAL ADRENALECTOMY: Used when all else fails. Immediate cortisol control. Risk: Nelson's syndrome (corticotroph tumor enlargement from loss of feedback — causes ACTH surge, skin hyperpigmentation) — monitor with MRI and ACTH levels post-adrenalectomy. RADIOTHERAPY: Stereotactic radiosurgery/conventional RT as adjunct after surgery. Response takes years. SECTION TITLED "SPECIAL POPULATIONS & COMORBIDITIES": CUSHING'S + DIABETES: Cortisol → hepatic gluconeogenesis + insulin resistance. Pasireotide worsens diabetes (70%). Metyrapone/Osilodrostat preferred if DM present. Standard diabetes management alongside. GLP-1 agonists and SGLT-2 inhibitors beneficial. CUSHING'S + HYPERTENSION: Cortisol activates mineralocorticoid receptors → sodium retention → hypertension. Spironolactone useful (aldosterone antagonist). ACE inhibitors/ARBs. Hypertension often resolves with cure. CUSHING'S + OSTEOPOROSIS: All patients need bone protection. Calcium 1000-1500mg + Vitamin D 800IU daily. Bisphosphonates if significant bone loss. DEXA at baseline. CUSHING'S IN PREGNANCY (rare): Adrenal adenoma more common cause in pregnancy. Metyrapone: preferred option (Ketoconazole teratogenic). Surgery safest in 2nd trimester if uncontrolled. ECTOPIC ACTH SYNDROME: Often from small cell lung cancer (aggressive) or carcinoid (indolent). Severe hypokalemia, very high ACTH, rapid onset. Bilateral adrenalectomy or medical therapy while treating primary tumor. POST-SURGICAL ADRENAL INSUFFICIENCY: Expect cortisol deficiency post-TSS. Start hydrocortisone replacement 15-20mg/day in divided doses. Taper slowly over 6-24 months as HPA axis recovers. Sick day rules essential.
